Sample sizes (dispersed seeds, adult plants) for seed dispersal distances parameters and genetic diversity indices for each plot are: Gran Canaria (326, 409), Tenerife (305, 778), and La Gomera (62, 397). Empirical values for dispersal distance parameters, % LDD, % SDD, and % immigration are indicated, and the bootstrapped estimates (and associated SD) are shown within brackets (different letters in superscripts indicate significant differences; see Methods). Genetic diversity indices are means ± 1 SE, and mean (95% CI) for effective population sizes.
